Název v původním jazyce

Mechanical wounding caused by inoculation influences the photosynthetic response of Nicotiana benthamiana plants to plum pox potyvirus

Popis výsledku v původním jazyce

Plants of Nicotiana benthamiana (Gray) (60 d old) were mechanically inoculated by a spreading of the fourth and fifth leaves with inoculum with or without plum pox potyvirus (PPV). Changes in growth parameters and selected photosynthetic characteristicswere followed in control and inoculated plants in the locally affected leaves (LA) during 11 d after inoculation (DAI), in systemically affected leaves immature at time of inoculation (SAI) during 14-25 DAI, and in systemically affected leaves developedafter the inoculation (SAD) during 28-39 DAI. The pure mechanical damage caused by inoculation induced a decrease in the net photosynthetic rate PN in LA and SAD leaves, and an increase in the steady-state value of the non-photochemical chlorophyll (Chl)fluorescence quenching qN. The qN increase appeared in certain time intervals in all measured leaves on plants, so that it could be regarded as indication of a systemic reaction of plant to the local mechanical injury. The viral infection
